中文摘要：
为了降低RoF系统中色散的影响,研究了基于OCS调制的RoF链路传输性能,并对不同基带码元传输脉冲抗色散能力进行了仿真。结果表明,高斯脉冲在光纤传输距离小于最大传输距离的1/2时,能够有效抵抗色散导致的码元时移效应,非归零码脉冲的抗色散能力相对比较稳定,适合长距离的传输。
英文摘要：
To reduce the dispersion effects in RoF system, the link transmission performance under OCS modulation was investigated and a simulation experiment aiming at comparing different baseband code transmission pulse ability in resisting chromatic dispersion was done. The results show that Gaussian pulse can effectively resist code time shifting effect induced by the dispersion when fiber transmission distance is less than half of maximum transmission distance. The non return to zero code pulse can resist dispersion stably, which is fit for long distance transmission.
